The simplest explanation is often overlooked. The SD card itself might be physically damaged. Look for any cracks, bends, or visible signs of wear and tear. Similarly, the SD card reader on your Lenovo laptop could have accumulated dust or debris, preventing a proper connection. A faulty connection is one of the major reasons.
Driver Problems
Drivers are the software that allows your operating system to communicate with hardware devices. Outdated, corrupted, or missing drivers for the SD card reader can prevent your Lenovo laptop from recognizing the SD card.
SD Card Compatibility and Formatting
Not all SD cards are created equal. Your Lenovo laptop’s SD card reader might not be compatible with certain SD card types, such as SDHC or SDXC cards with extremely large capacities. Furthermore, if the SD card is formatted with a file system that your laptop doesn’t support (like exFAT on an older system), it may not be recognized.
Operating System Issues
Sometimes, the problem lies within the operating system itself. Glitches, bugs, or outdated operating system versions can interfere with the detection of external storage devices like SD cards.
Hardware Malfunction
In rare cases, the SD card reader on your Lenovo laptop might be physically damaged or malfunctioning. This is a more serious issue that might require professional repair. This could also mean the SD card reader is not getting enough power from the motherboard.
